My understanding is base events defined in RFC6470 is unchanged, but if we want to see base events defined in RFC6470 also applicable to New NMDA datastores, I think these existing base event may need to be updated as well, to indicate specific NMDA datastore that need to be changed, e.g., netconf-config-change However based on our analysis, netconf-config-change is only applicable to <running> and <startup> . <intended> and <operational> is read only and Can not be changed by user in a specific management session. Other base events doesn't have datastore leaf. Therefore base event defined in RFC6470 Can keep as it does. Hope this answer your question.

Qin/All,

So if we don't bis6470 then how do we handle the datastore leaf in RFC6470 not supporting the new NMDA data stores?

Tim

Subject: RFC6470bis vs New draft on NMDA Base Event

One issue raised in last meeting what need to be modified in RFC6470 to support NMDA and whether it is a good idea to make bis for RFC6470 to cover additional new event related to NMDA. 

The con:
republish YANG notifications that are not changing is not a good idea NMDA event not specific to NETCONF, although RFC6470 allows NETONF Base Event applied to non-Netconf session by setting session-id to zero.
NETCONF session without NMDA support can not understand new NMDA event.
The Pro:
One Base Event notification module cover all events which help monitor lifecycle of Netconf session change.

After discussing with RFC6470 author, we decide to separate NMDA notification from NETCONF base event notification. 
Comments or suggestions if you have different opinion.

Hi, folks:
We rewrite NMDA Base Event draft based on last meeting discussion in the netconf session and re-scope to NMDA specific Base Event Notification definition. 
The changes include:
1. remove ietf-netconf-data-change notification which has potential overlapping with YANG push on change update mechanism.
2.Add NMDA data validation notification to keep track of the validation result of <intended> data-store and  the reason why the configuration were not applied.
3. Problem space change in the introduction.
https://www.ietf.org/rfcdiff?url2=draft-wu-netconf-base-notification-nmda-01

We would like to request WG to adopt this draft. Please indicate if you like this draft or idea.
Many thanks.

Abstract:
   The Network Configuration Protocol (NETCONF) provides mechanisms to
   manipulate configuration datastores.  NMDA introduces additional
   datastores for systems that support more advanced processing chains
   converting configuration to operational state.  However, client
   applications are not able to be aware of common events pertaining to
   additional datstores, such as a data validation state change in
   NETCONF server, that may impact management applications.  This
   document updates [RFC6470] to allow a NETCONF client to receive
   additional notifications for some common system events pertaining to
   the Network Management Datastore Architecture (NMDA) defined in
   [RFC8342].

                                                                                  


Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
